Pakatan Harapan candidate for the Tanjung Piai parliamentary by-election Karmaine Sardini says he is inspired by Tun Dr Mahathir Mohamad in continuing to serve the people, despite certain parties, including the opposition, raising questions over his age.

The Tanjung Piai Parti Pribumi Bersatu Malaysia (Bersatu) chief said in fact, he considered such jibes as a challenge for him to work harder to win over voters and in continuing to provide the best service to the local community.
